Definitions

  • the invention relates to meters intended for measuring a flow rate of working fluid (a gas or a liquid) passing through their inner cavity and having the features described in the claims.
  • Meters operating on the specified volumetric principles are mechanical turbine meters and rotary type meters.
  • the advantage of mechanical meters is their resistance to disturbances and distortions in the flow of the fluid passing through them, as well as resistance to changes in the flow direction.
  • the main drawback of the mechanical method of measurement carried out by said meters is the presence of moving parts making them sensitive to dirt and prone to wear and tear of their parts arranged directly in the flow.
  • the diagnostic capabilities of mechanical meters can not be implemented in such volume as that of the electronic ones that does not ensure the required operational control of their metrological and technical characteristics.
  • ultrasonic meters As an alternative to mechanical (turbine and rotary) flow meters, ultrasonic meters based on scanning the flow velocity by ultrasonic pulses may be applied. Ultrasonic meters are free from moving and mechanical parts. The disadvantage of ultrasonic meters is their significant sensitivity to flow disturbances. For this reason, in order to achieve higher accuracy, it is required to use flow conditioners or long straight inlet pipelines requiring large measuring space that is not always feasible.
  • said meters require adapters—devices designed to create a uniform flow of gas in order to isolate and protect flow velocity sensors from the turbulence (asymmetry) affecting accuracy of measurement.
  • the application of said adapters creates a significant challenge with domestic gas meters of a small cross section and sensitivity to the pressure drop due to the use of said adapters.
  • Using adapters also causes serious problems in case of their application with industrial meters whose high flow rate requires an increased strength of adapters to withstand stresses and noise caused by the flow to be measured. This limitation takes place mainly due to the high energy of the flow.
  • the known solutions are extremely sensitive to disturbances caused by asymmetrical constrictions that normally occur in valves of pipelines particularly if they are located in the immediate vicinity of the sensor—typically quite close to the meter inlet.
  • One of the known prior art solutions which eliminates the above disadvantages are meters consisting of a housing with one or a plurality of mass flow sensors (patent EP 2 824 432 A2).
  • the total flow in these meters is substantially divided into a plurality of smaller flows wherein each is measured by a mass flow sensor of corresponding size.
  • This solution has a very complex construction and is costly because of the plurality of flow sensors required for measuring high flow rates and volumes of gas, and thus has limitations for their application as small (domestic) meters.
  • the above solution also has the lowest limit of “internal scalability” of a flow sensor as flow sensors must be designed and manufactured for each individual class of the meter.
  • the main objective of the present invention is to provide such an apparatus which allows overcoming the above limitations and problems. This is achieved by a fluid flow meter with configuration of flow generation and flow sensor.
  • the given meter is designed in accordance with the features contained in claim 1 of the following claims.
  • the invention is a fluid meter comprising a housing with an inner chamber, which is made in the form of a cylinder with a uniform rounding of one of the bases.
  • the rounded base has a curved inward part and allows the formation of a fluid flow.
  • the meter contains a flow sensor arranged inside the housing and used for measuring flow velocity of the fluid.
  • the fluid meter has an adapter for adjusting different diameters of flow sensors and an outlet of the meter.
  • the fluid meter contains a flow preparation device for dissipating and stabilizing the flow of the measured fluid.
  • the fluid meter has an inlet for directing the fluid flow into the chamber of the meter housing, an outlet for outputting the fluid flow from the meter, an electronics unit, a coarse filter, a shut-off valve and a fluid leak detection sensor.
  • the inner chamber at the inlet of the flow sensor has the bell-like funnel shape, which forms a flow at the inlet of the flow sensor.
  • the adapter is adjustable and the transition mechanism adapts to the diameter of the flow sensor used.
  • the advantage of the first claim of the invention is the configuration of the meter with the features contained in claim 2 , when the flow sensor is located in the center of the chamber along its cylindrical axis.
  • the inner surface of the chamber and the outer surface of the flow sensor form a channel, when passing through which the measured fluid forms a steady homogeneous laminar flow.
  • claim 2 is the configuration of the meter with the features contained in claim 3 , when the transition device is used for adjusting the flow sensor diameter and the meter outlet, and which is located in close proximity to the outlet, which results in a compact form of the meter.
  • claim 3 is the configuration of the device with the features contained in claim 4 , when the inner chamber has a flow preparation device in the shape of a grid at its bottom. This device divides the inward fluid flow into multiple separate streams passing through the chamber. Thus, a stable homogeneous flow is being formed.
  • Claim 4 of the preferred embodiment with the features contained in claim 5 shows a fluid leak detection sensor which ensures the safety of the device by detecting the fluid leakage from the meter, actuation of the shut-off valve and stopping the working fluid supply to the meter.
  • Claim 5 of the preferred embodiment with the features contained in claim 6 describes the meter housing, whose cross-sectional area is many times (not less than 10 times) larger than the cross-sectional area of the inlet channel of the meter and the inlet of the flow sensor, which significantly reduces the influence of the external disturbing factors and provides high-precision measurements.
  • claim 6 of the preferred embodiment with the features contained in claim 7 is the configuration of the meter which allows to use a flow sensor of any operating principle, thus ensuring the versatility of the meter.
  • FIGS. 1-4 illustrate the invention which overcomes disadvantages of the prior art inventions—a compact fluid flow meter with configuration of flow generating and flow sensor.
  • FIGS. 1-4 illustrate:
  • FIG. 1a-1b housing 2 inner chamber 3 depression 4 flow sensor 5 adapter 6 flow preparation device 7 main inlet 8 outlet 9 electronics unit 10 coarse filter 11 shut-off valve 12 fluid leak detection sensor
  • a fluid flow meter with configuration of flow generation and flow sensor for measuring flow velocity and flow rate of a fluid is a device comprising the following components ( FIGS. 1 a -1 b ):
  • FIG. 1 illustrates, as an example of the invention, a stationary meter with configuration of flow generation and flow sensor for measuring the flow velocity and the flow rate of the working fluid.
  • the invention relates to flow meters intended for measuring the fluid flow with measurement based on volumetric principles.
  • the invention relates to meters for not only domestic application (e.g., G4/G6 nominal sizes), but also for measuring high flow rates, i.e., for industrial meters of G10, G16, G25, G40 nominal sizes etc. (where, for example, nominal size G25 denotes a flow rate up to 48 m 3 /h).
  • the invention relates to meters with a remote control of their functionality which include electronic remote control systems requiring the application of pressure and temperature sensors, as well as additional volume correctors to compensate for the errors of approximation arising from temperature and pressure fluctuations.
  • the operating principle of the meter is as follows:
  • FIG. 2 illustrates a schematic view (top view) of a flow preparation device.
  • the flow preparation device ( 6 ) is a grid arranged at the bottom of the cylindrical part of the chamber ( 2 ) such that the fluid to be measured through the inlet ( 7 ) passes through the flow preparation device ( 6 ) and falls into the chamber ( 2 ) of the meter housing ( 1 ).
  • the grid of the flow preparation device is a set of at least 21 blades with such dimensions to not overlap more than 23% of the total cross sectional area of the chamber ( 2 ).
  • the flow preparation device ( 6 ) performs flow dissipation of the fluid to be measured providing conditions for creating a uniform and steady flow, and thus substantially reduces the effects caused by the high energy of the turbulent flow at the inlet of the flow sensor ( 4 ).
  • the meters based on volumetric principles are prone to errors caused by the gas flow distortion in the pipeline due to various destabilizing factors known as local resistance (faucets, valves, switches, pipe bends, constrictions and expansions of the pipeline, the diameter changes, temperature and pressure gauges taps etc.).
  • the flow sensor ( 4 ) is a measuring element (a sensor, a flow tube) of volume flow or flow velocity of any operating principle.
  • the sensor is located in a cylindrical chamber ( 2 ) of the meter housing ( 1 ) so that the fluid to be measured passes from the inlet ( 7 ) through the flow preparation device ( 6 ), is further dissipated into a plurality of flows, passes through the chamber ( 2 ), flows around the depression ( 3 ), combines in the center of the chamber ( 2 ) into a uniform stable flow which passes through the flow sensor ( 4 ) and exits the meter through the outlet ( 8 ).
  • any known measuring devices of volume flow and flow velocity of volumetric or mass operating principle may be used as the flow sensor. Therefore there is no need to further describe this flow sensor ( 4 ).
  • the flow sensor ( 4 ) detects the data directly or indirectly indicating the amount of fluid flowing through the pipe and through the meter. These data are transmitted by the flow sensor ( 4 ) to the electronics unit ( 9 ) of the meter for further processing and recording (storing).
  • the distinguishing feature of the meter is the presence of the adapter ( 5 ) arranged in the inner lower part of the housing (after the flow sensor outlet) intended for adjusting the diameter of the flow sensor ( 4 ) and the meter outlet.
  • the adapter allows to arrange in the meter flow sensors of different diameters depending on the desired range of measured flow.
  • a schematic sectional view of the adapter is shown in FIG. 3 .
  • the inlet ( 7 ) of the fluid flow is an orifice, a channel directing the fluid flow into the chamber ( 2 ) of the meter housing ( 1 ).
  • the output channel ( 8 ) is intended to output the fluid flow exiting the chamber ( 2 ) of the meter housing ( 1 ).
  • the electronics unit ( 9 ) is intended to detect the data transmitted from the flow sensor ( 4 ), processing, recording (storing) of these data and their processing results and electronic control.
  • the type of the electronics unit ( 9 ) may vary depending on the implementation requirements and causes no significant influence on the present invention.
  • the electronics unit ( 9 ) is connected to the flow sensor ( 4 ) by means of a physical data link (the term “physical data link” is herein referred to a line of one or several solid connectors (such as plugs, wires) or a wireless communication line (radio, Bluetooth etc.).
  • FIG. 1 a shows an embodiment in which the electronics unit ( 9 ) is arranged on the outer side of the meter housing ( 1 ).
  • the coarse filter ( 10 ) is arranged at the meter inlet and is intended to purify the fluid of impurities that can clog or damage the flow sensor ( 4 ) or the flow preparation device ( 6 ).
  • the shut-off valve ( 11 ) is arranged at the inlet ( 7 ) and provides the overlap (cut-off) of the fluid flow on a signal received from the electronics unit ( 9 ).
  • the fluid leak detection sensor ( 12 ) is intended to provide detection of the fluid leakage from the meter, actuation of the shut-off valve ( 11 ) and stopping the working fluid supply to the meter. This sensor is essential for operating safety of combustible media meters the leakage of which can lead to an accident and serious consequences.
  • the housing ( 1 ) consists of two parts ( FIG. 4 ):
  • FIG. 4 shows with arrows the direction of rotation of the moving parts of the housing and the electronics unit.
